CARL WILIIELM IILSCI'IEUR, OF BARMEN, GERMANY.

REEL FOR WINDING-MACHINES.

To all whom it may concern:

Be it known that I, CARL WILIIELM PIL- scIinUR, a citizen of the German Empire, residing at Barmen, in the Province of Ithenish Prussia and Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Reels for Winding-Machines; and I- do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same.

Reels (whims) for winding machines in the case of which the arms or s okes forming the reel roper are connected y elastic bridges whici serve as yarn-carriers are already well-known. Very recently such bridges have been frequently made from endless rubber bands, each of which is placed round a )air of spokes and tightened. The flexibility of these rubber bands is suflicient to satisfy requirements but said bands possess the defect that said flexibility does not last long, as the rubber bands soon become torn during use so that they lose in elasticity and become slack, so that the bridges are not able to offer suilicient resistance to the pressure of the skeins of yarn restin on them and to the tension which exists during unwinding and the result being that they lide down on the s okes towards the axle o the reel. This gli( ing down action of the bridges is non-uniform in correspondence with the varying tension at various moments during one revolution. The bridges set themselves at various heights, 'i. e. at various distances from the axle so that not only does the reel runirregularly and jerkin ly the result of which is that 100 s are ormed and that breakages occur, ut also the la ers of thread possess a non-uniform perip ier The reel forming the subject-matter o the present invention is intended to do away with these defects. It is distinguished b a new kind of yarn-carrier which is forme( of two rubber rings which are placed on the spokes and are connected by a bridge which is suitably elastic, the rubber rings embracing the spokes firrnl all round and making the displacement of the arm-carrier independent of the nature am of the flexibility of the elastic intermediate member or of the tension in the yarn while being unwound.

Patented March 10, 1908.

Serial No. 386,993.

In the accompanying drawing the subjectmatter of the present a plication is represented by way of examp e, one embodiment being shown.

In said drawings: Figure 1 is a side elevation of the reel, I ig. 2 is a front elevation of the same, Fi 3 an elevation of a single arm-carrier drawn to a larger scale, and ig. 4 a plan of the same.

The reel consists of the axle 1 provided with lateral pivots 2 and with the spokes or arms 3 which are inserted radially in the nave on the axle. The yarn-carriers servim to hold the yarn skeins wound upon the rec consist each of two rubber rings 4, 4 the internal opening of which is smaller than the cross section of the spokes and of a brid e 5 which is likewise suitably elastic. The Iaridges connect said spokes in pairs the length of said bridges corresponding with the distance apart of the spokes. In order to be able to fulfil this condition in each case said bridges may if desired be adjustable in length and ma be surrounded with cylindrical sheaths tor the purpose of projecting the yarn. These yarn-carriers thus 'orrned are placed with tieir rubber rings on the s okes, the rings contracting tightly round t ie latter and so giving to the arn-carrier suilicient held against the tension and the weight of the yarn so that the bridges are prevented from shifting and sliding towards the axle during the winding-on process. The bridges connecting the rubber wings ma themselves consist of any suitable material, such as wire, strips of sheet metal, and so on, the bent-over ends 6 of which are for example hooked in the simplest manner into the reels.

Having now described my invention I declare that what I desire to secure by Letters Patent is:

1. Reel for winding-machines comprising in combination a revoluble nave, a pluralit of radial spokes arranged at opposite en l s of the nave the spokes at one end being opposite those at the other end, a rubber ring on each spoke near its outer end, and a bridge interconnecting the rubber rings on each pair of spokes situated opposite one another.

2. Reel for windin -n1achines comprising in combination a revo uble nave, a pluralit of radial spokes arranged at opposite en s of the nave the spokes at one end being opname to this specification in the presence of posite those at the other end, a rubber ring two subscribing witnesses.

on each spoke near its outer'end and an elastic brid e interconnecting the rubber CARL WILHELM PILSCHEUR' 5 rings on eac h pair of spokes situated oppo- WVitnesses:
